Welcome to the Sandcastle Help File Builder
Sandcastle, created by Microsoft, is a tool used for creating MSDN-style documentation from .NET assemblies and their associated XML comments files. The current version is the May 2008 release. It is command line based and has no GUI front-end, project management features, or an automated build process like those that you can find in NDoc. The Sandcastle Help File Builder was created to fill in the gaps, provide the missing NDoc-like features that are used most often, and provide graphical and command line based tools to build a help file in an automated fashion.Tip: See the Installation Instructions for information about the required set of additional tools that need to be installed, where to get them, and how to make sure everything is configured correctly.
Tip: If you are new to Sandcastle and the help file builder, see the topics in the Getting Started section to get familiar with it, set up your projects to produce XML comments, and create a help file project.
